Design Systematic review with random-effects meta-analysis and meta-regression. Data sources Eight online databases were searched up until 12 January 2024. Eligibility criteria Studies of all designs in all languages were eligible (except case studies and reviews) if they contained information on the population (postpartum people), intervention (frequency, intensity, duration, volume, or type of exercise, alone (‘exercise-only’) or in combination with other intervention components (eg, dietary; ‘exercise+co-intervention’), comparator (no or low volumes of physical activity), and outcomes: hypertension, diabetes, cardiometabolic risk factors (systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol, high density lipoproteins, low density lipoproteins, and triglycerides, glycated hemoglobin (HbA1C), glucose and insulin concentration), breastfeeding (breast milk quality and volume), infant growth (length and weight) and development, or postpartum injury. Results 46 unique studies (n=8766 participants) from 20 countries were included. Moderate certainty of evidence showed exercise+co-interventions reduced the odds of developing diabetes by 28% (7 randomised controlled trials (RCTs), n=2496; OR 0.72 95% CI 0.54, 0.98, I2 12%), reduced SBP (10 RCTs, n=2753; mean difference (MD) −2.15 95% CI −3.89 to –0.40, I2 73%) and DBP (9 RCTs, n=2575; MD −1.38 95% CI −2.60 to –0.15, I2 66%) compared with controls. Infant growth and development, breast milk quality and quantity, and risk of injury were not different between exercise and control groups.

The important thing is not to stop questioning’ (Albert Einstein). On 14 and 15 November 2024, Sport and Exercise Medicine in Switzerland (SEMS) will host a special SEMS annual meeting, celebrating 75 years of sports medicine in Switzerland. While we all consider SEM a young specialty, one that is still not recognised as a full medical specialty in many countries around the world (including Switzerland), we also must acknowledge the trailblazing efforts of European countries at the start of the 20th century to bring SEM to life. In 1928, Switzerland hosted the St Moritz Winter Olympic Games. The event gave the impetus to the reunion of pioneers from 11 European countries, which led to the formation of the ‘Association Internationale Médico-Sportive’ (AIMS; today Fédération Internationale de Médecine du Sport or FIMS), with a Swiss as its first President. It would, however, take 20 or more years for most countries to develop national organised SEM societies, due to the troubled 1930s and 1940s.

{"title":"Barriers and enablers of adherence to high-intensity interval training among patients with cancer: a systematic review and meta-analysis","authors":"Behnaz Mahdaviani, Maryam Selk-Ghaffari, Mojdeh Sarzaeim, Jane S Thornton","doi":"10.1136/bjsports-2024-108163","DOIUrl":"https://doi.org/10.1136/bjsports-2024-108163","url":null,"abstract":"Objective Physical activity confers physical and psychosocial benefits for cancer patients and decreases morbidity and mortality, but adherence varies. High-intensity interval training (HIIT) is time-efficient and may improve adherence. Our aim was to determine barriers and enablers of adherence to HIIT in patients diagnosed with cancer. Design Systematic review and meta-analysis. Data source PubMed-MEDLINE, Scopus and Web of Science. Eligibility criteria Intervention studies including patients diagnosed with any type of cancer, who engaged in HIIT with or without co-intervention in any stage of treatment and have reported outcomes for adherence. Results Eight hundred articles were screened and 22 were included (n=807); 19 were included in the meta-analysis (n=755). Weighted adherence to HIIT was 88% (95% CI, 81% to 94%). None of the studies reported serious adverse events. Although being a woman and having breast cancer were associated with lower adherence (p<0.05), age was not (p=0.15). Adherence was significantly lower during the treatment phase in comparison with pre- and post-treatment phases, 83% versus 94% and 96%, respectively (p<0.001). Session time of more than 60 min, when unsupervised and combined with other interventions, was associated with decreased adherence (p<0.05). Conclusion Adherence to HIIT programmes among cancer patients varies and is improved when the intervention is supervised, of shorter duration, consists of solely HIIT and not in combination with other exercise and occurs during pre- and post-treatment phases. Strategies to improve adherence to HIIT in specific subpopulations may be needed to ensure all patients with cancer are provided optimal opportunities to reap the benefits associated with physical activity.

The WHO advocates for distinct recommendations for each country to address variation in needs, resources and context. Specific regional recommendations for three underactive populations facing unique barriers to movement are lacking—people with chronic conditions, disability and advanced age. We review which countries/regions provide specific physical activity guidelines for these populations to identify deficiencies in meeting WHO recommendations and inform future directions for guideline development. Design Scoping review. Data sources OVID Medline, PubMed, Scopus, Embase, Web of Science, Google Scholar, ProQuest, CINAHL, Google searches, targeted websites. Eligibility criteria Data sources were searched from database inception to September 2023 to identify community-facing physical activity guidelines at the national/international level for these populations. We recorded, summarised and analysed physical activity guideline recommendations extracted from published guideline documents, organised by population and country/region. Results 66 articles were identified, addressing 28 distinct countries/regions, including four international guidelines, published from 2009 to 2023. The WHO guidelines were adopted by 19 countries and the European Union. Across all regions, a lack of specific advice was identified for individuals with chronic conditions (46%), disability (46%) and advanced age (11%). Advice for chronic conditions and disability commonly replicated general adult population advice. Conclusion Many countries/regions do not produce physical activity guidelines specific to populations with chronic conditions and disability. As such, a large proportion of countries/regions failed to meet WHO recommendations, highlighting a lack of customised advice to address unique barriers faced by vulnerable populations.

Methods Randomised controlled trial including 140 participants, with a degenerative meniscal tear and no or minimal radiographic OA changes. Participants were randomised to either APM or 12 weeks of exercise therapy (1:1 ratio). The primary outcome was knee OA progression assessed by the Osteoarthritis Research Society International (OARSI) atlas sum score (sum of medial and lateral compartment joint space narrowing and osteophyte score). Secondary outcomes included incidence of radiographic and symptomatic knee OA, patient-reported pain and knee function and isokinetic knee muscle strength. Results The adjusted mean difference in change in the OARSI sum score was 0.39 (95% CI −0.19 to 0.97), with more progression in the APM group. The incidence of radiographic knee OA was 23% in the APM group and 20% in the exercise group (adjusted risk difference 3% (95% CI −13% to 19%)).

Methods This study followed the COnsensus-based Standards for the selection of health Measurement INstruments guidelines. An 18-item preliminary version of the Back pain Knowledge and beliefs Survey (BacKS) was generated based on evidence-based key messages and current clinical guidelines for low back pain. Four items were added following input from three consumers and seven experts. Focus groups (n=9) confirmed content validity. The 22-item version was completed by 258 Australian-based adults (>18 years) with self-reported low back pain. A follow-up survey was sent 1 week later. The following measurement properties were evaluated to produce, and then assess the final version of BacKS: structural validity (exploratory factor analysis); internal consistency (Cronbach’s alpha); test–retest reliability (intraclass correlation coefficient); measurement error (Smallest Detectable Change); construct validity (hypothesis tested: moderate positive Pearson correlation between BacKS and Back Beliefs Questionnaire); plus, interpretability and feasibility. Results The final BacKS comprised 20 items with a 2-factor structure (biomedical factor: 9 items, score ranging from 9 to 45, and self-care factor: 11 items, score ranging from 11 to 55). Internal consistency and reliability were adequate (>0.70) for each factor. Smallest detectable change was 4.4 (biomedical factor) and 7.0 (self-care factor). Our construct validity hypothesis was confirmed (Pearson correlation=0.53). No floor or ceiling effects were detected.
